NLM Classification 2014 Edition

The NLM Classification, available online at
http://www.nlm.nih.gov/class/, incorporates all additions and changes to the
schedules and index from April 2013 through March 2014. The PDF version will be updated with 2014 classification data by the end of May 2014.

The QS (Human Anatomy) and QT (Physiology) schedules were the major area of focus for the 2014 edition.

Some QS and QT class number captions and notes were revised to better reflect the scope of the number. For example:

At QS 26.5, the note was added: Classify here works on Visible Human Projects.

At QS 504, the note was added: Includes works on comparative histology between humans and animals.

At QS 645, the caption was changed from Placentation. Fetal membranes to Placentation. Extraembryonic membranes.

At QT 4, the caption was changed from General works, including comparative physiology to General works. The note was changed from Classify material on comparative physiology limited to animals in QP to Includes works on comparative physiology between humans and animals. Classify material on human physiology only in QT 104. Classify animal physiology in QP, QL, or SF.

At QT 34, the caption was changed from Biophysics to Biophysical phenomena.

At QT 36, the caption was changed from Biomedical engineering to Bioengineering. Biomedical engineering (General).

At QT 36.5, the caption was changed from Nanotechnology to Microtechnology. Nanotechnology.

At QT 150, the caption was changed from Hot climates to Hot temperature.

At QT 250, the caption was changed from Recreation. Outdoor activities to Leisure activities.

At WD 610, the caption was changed from Hot Temperature to Heat stress disorders.

At WN 600, the note was added: Classify works on the effects of non-ionizing radiation on humans in QT 162.U4.

All index entries pertaining to the aforementioned schedule additions and changes were modified.

Changes to the Index

One hundred and five (105) new index entries were created of which forty-two (42) are from the 2014 MeSH; the remainder are MeSH terms from previous years. All main index headings are now

Numerous main index entries and cross references were
modified to reflect changes in the MeSH vocabulary. For example:

Biological Agents was deleted as a main heading and made a
cross reference to Biological Factors.
